The City Council has determined that a single source is required for the
,stablishment of a "Council Policy" regarding rights -of -way requirements and
general standards for public improvements installed thereon, whether work is
done under a subdivision agreement, a public improvement permit, a 1911 Act
contract or other form of City contract.
PURPOSE
This policy, pertaining to public rights -of -way and public improvements
thereon, is adopted to outline the characteristics of the several categories of
public rights -of -way and to prescribe the general standards for public improve-
ments installed on such rights -of -way.
POLICY
I. PUBLIC RIGHTS -OF -WAY
1. Public rights -of -way shall conform to the standards prescribed below,
except:
--'.� a) Where the front property line, abutting the public street for which
improvements are required, is in a common line with the prolongation
of fifty (50) percent or more of the property lines of the other lots
in the block, and where no Specific Plan applies thereto, dedication
of public street rights -of -way to meet such prolongation is required.
b) Where the rear property line, abutting the alley for which improvements
are required, is in a common line with the prolongation of fifty (50)
percent or more of the property line of the other lots in the block, and
where no Specific Plan applies thereto, dedication of public alley rights -
of -way to meet such prolongation is required.
q
c)
Where in the opinion of the City Engineer unusual circumstances
warrant departures, the City Engineer may submit drawings, comments
and recommendations to the Director of Planning for possible inclusion
in the Specific Plan. The Director of Planning shall submit such
drawings, comments and recommendations, to the Planning Commission.
The Director of Planning may submit, along with such drawings, com-
ments and recommendations of the City Engineer, his own comments and
recommendations. The Planning Commission nay then make there deter-
mination as to the inclusion or exclusion of such rights -of -way re-
quirements to the Specific Plan.
